IPC: G01N29/04
Filed: 1992-03-30
Abstract: PURPOSE:To nondestructively judge the adhesive state of a two-layer tube by comparing both echo decibel values of the boundary face reflection on the boundary face of both inner and outer layers and the bottom face reflection on the inner periphery of the two-layer tube from the ultrasonic signal transmitted to the inside of the tube from the outside. CONSTITUTION:A ultrasonic signal is transmitted to the inside of a two-layer tube from a ultrasonic probe at the outside, the decibel value (a) of the boundary face reflected echo and the decibel value (b) of the bottom face reflected echo are measured, and the ratio b/a of them is obtained. The value of the ratio b/a is relatively large when the boundary face is sufficiently stuck, and the value is relatively small otherwise. The value of b/a corresponding to the minimum condition to assure the adhesion of the boundary face is set in advance, it is compared with the measured b/a value, and the adhesive state is judged as unsatisfactory when the latter is smaller than the former.

Filed: 1982-04-28
Abstract: PURPOSE:To enhance the feeding accuracy by a structure wherein a means to change the parallelism between a feed screw and a guide way is provided in order to effectively change the cumulative lead of the feed screw by positively changing the parallelism therebetween.
